Lux Renovations, LLC exclusive provider of the Owens Corning Basement Finishing System, has been serving New England homeowners since 2002. Our dedication to customer experience and satisfaction has won us Owens Corning's top customer service ranking nationally for the last 17 years in a row. Something like that doesn't happen by accident. We are committed to insuring that all of our customers describe their experience with us as "the best contractor experience I ever had". If you are considering a basement finishing project please allow us to show you how Owens Corning has changed the industry with this unique system. A free consultation and design is always available.

"Overall, the finishing of my basement went pretty smooth. The Owens Corning product, drop down ceiling, and flooring are all really sharp. In the beginning everything went fast and smooth with the framing and wall/floor/ceiling install being done within 2 weeks. There were some hiccups with minor imperfections, tv mount in wrong spot, etc. Those were fixed promptly. After that is when I ran into issues with other items in my contract that were not taken care of and the project felt forgot about. Just had some minor electric work, stairs to get carpeted, and didn't receive hanging clips yet. I had to constantly ask about these items and every answer would be "I forgot to ask or send the clips". I eventually got the items completed, but am not happiest that it took almost a month and constant reminding to get these items that should've been scheduled for during the project."

FAQs for basement remodeling projects in South Portland, ME

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
